Overview
The DDTA115ECA-7-F is a PNP pre-biased small signal surface mount transistor from Diodes Incorporated, housed in an SOT-23 package. It features built-in biasing resistors where R1 equals R2, with a nominal resistance of 100 kOhms each. The device supports a maximum collector-emitter voltage (VCEO) of -50 V and a continuous collector current of -100 mA. Power dissipation is rated at 200 mW, with an operating temperature range spanning from -55°C to +150°C. The component includes a gain-bandwidth product of 250 MHz and meets AEC-Q101 standards for high reliability.
Feature Summary
- Epitaxial planar die construction with integrated equal-value biasing resistors
- Qualified to AEC-Q101 automotive standards for high reliability applications
- Totally lead-free and fully RoHS compliant with halogen and antimony free green device composition
Applications
- Automotive electronic circuits requiring AEC-Q101 compliance
- General purpose switching and amplification tasks
- Driver circuits for logic level translation
Procurement Notes
Verify the specific ordering suffix matches the required packaging quantity and reel size before procurement. Confirm that the active status aligns with long-term production availability needs. Ensure compliance requirements such as RoHS 3 and PPAP capability are documented for your supply chain records. Cross-reference the date code marking system to verify manufacturing timelines upon receipt.
Selection Notes
Select this component when a PNP configuration with matched internal biasing resistors is required. The 100 kOhm resistor value suits moderate drive current applications. Consider the SOT-23 footprint for space-constrained PCB layouts. Verify input voltage limits against your circuit's maximum signal levels to prevent breakdown.
Part Context
This part belongs to the DDTA series of pre-biased transistors manufactured by Diodes Incorporated. It is specifically designated within the R1 = R2 subgroup, distinguishing it from variants with unequal resistor ratios. The ECA suffix indicates the SOT-23 case style and specific compliance markings used by the manufacturer.
Replacement Considerations
Direct substitutes include other DDTA115 variants with different resistor values or packages. For automotive replacements, consider the ADTA114ECAQ series if pin compatibility allows. Verify electrical parameters match exactly when swapping between different resistor ratio families.
